Channel Samples at Midnight Owl Return Excellent Lithium Grades and New Target Identified at The San Domingo Pegmatite Project

Bradda Head Lithium Ltd (AIM:BHL, TSX-V:BHLI,), the North America-focused lithium development group, is pleased to announce the results from surface samples at the San Domingo ("SD") pegmatite project in central Arizona. New channel samples at the Midnight Owl target contain high grade intercepts of 8.40 meters of 1.17% Lithium Oxide ("Li2O") with 623 ppm Cs (Cesium) and 625 Ta2O5 (Tantalum Pentoxide). A new target, Ruby Soho, was also discovered as part of the Company's follow-up on anomalous soil samples.

Channel and Grab Sample Highlights:

  • 8.40m @ 1.17% Li20 with 623 ppm Cs and 625 Ta2O5 at Midnight Owl
  • Seven grab rock samples ranging from 0.25% to 3.57% Li20 on newly discovered Ruby Soho Pegmatite
  • Grab sampling identifies 3.97% Li2O on spodumene-bearing pegmatite outcrop at the Thunder target
  • The abundance of Cs and Ta present in the Midnight Owl Samples holds potential for excellent by-products (Ta2O5 at $300/kg, CsCO3 at $142/kg)
  • Both Ruby Soho and Thunder are accessible by road, with clear drill targets emerging
  • Bradda's management believes that with the completion of the next drilling program, there will be sufficient data to develop a 43-101 compliant resource on not only one but several pegmatite bodies

Project Highlights

  • New channel sampling from the Midnight Owl target reveals significant lithium mineralization zones outside the main mine cut and on historic benches near drill holes SD-22-03, 04, and 05 (PR 06 February, 2023). As reported, Holes 03 and 05 contain 5.36m at 1.20% and 4.27m at 1.86% Li2O starting from surface, and appear to represent different portions of the same pegmatite.
  • These new Midnight Owl channel samples also contain exceptional Cesium at 623ppm and 625 Tantalum Pentoxide, both critical metals for the Department of Energy ("DOE") and potential byproducts at San Domingo.
  • Additional nearby rock chip samples located 35m to the southwest on the same bench contain 2.40%, 1.17%, and 0.61% Li2O from outcrops with visible spodumene and lepidolite.
  • A new target called Ruby Soho was discovered about 1.5km east of Midnight Owl and mapping reveals a single pegmatite running 1.5 to 5.0m in width and exposed for over 250m, containing abundant visible spodumene.
  • Seven grab samples from Ruby Soho have a range of 0.25% to 3.57% Li2O and clearly represent a new target that is accessible by road.
  • A previously identified target, Thunder, was sampled, identifying outcrops with excellent high grades with one sample returning 3.97% Li2O. The target has not been drill-tested and has road access.

Ian Stalker, Executive Chair, commented:

"The identification of exceptional lithium values on new and older targets illustrates the ever-present and shallow potential for discovery of lithium mineralization at San Domingo. We continue to discover excellent mineralization on the surface around the Midnight Owl prospect and these new channel samples demonstrate that the potential for shallow, open cut mining is possible at San Domingo. Furthermore, the highly elevated cesium values constitute a highly strategic opportunity at San Domingo as the element is a distinctly sought after by the DOE and is a critical metal as designated by the USA."

Midnight Owl Channel Samples

A total of 15 new channel samples were collected at Midnight Owl on a historic bench (or hillside bulldozer cut) in pegmatite outcrop, exposing large spodumene crystals. Several large spodumene were newly exposed in outcrop upon clearing vegetation growing alongside the bench and determined to be significant, warranting channel sampling. The channel sampling returned promising values over the 8.40m with 1.17% Li2O and a remarkable 623ppm Cs and 625 Ta2O5. The samples were collected across a pegmatite exposure that represents surface mineralization potentially correlative with shallow lithium intercepts in 2022 core holes, 20 meters to the northwest. As reported on 6 February 2023, the holes, SD-22-03, 04, and 05, encountered 5.36m, 3.29m, and 4.27m of 1.20%, 1.01% and 1.86% Li2O respectively from surface, potentially suggesting sub-horizontal lithium mineralization in this pegmatite body. The prior channel sampling in the Midnight Owl Pit (PR 08 April, 2024) highlighted 2.90 meters of 2.31% Li2O, but has different structural context to the new channel sample results and appears to represent a separate pegmatite body.

The Company is conducting a re-interpretation of the shallow drill hole segments at Midnight Owl in context of the surface data as there is the potential for a broader, sub-horizontal lithium mineralized body. The pegmatite covering this area on surface measures 250 meters long by 80 meters in width. Thickness of the sub-horizontal and lithium mineralized pegmatite is interpreted to vary between 5 and 10 meters. Further detailed mapping is planned to ascertain better geologic and structural context and aid interpretation with re-examination of the drill core for structural data.

Lone Giant Channel Samples

Channel sampling conducted at Lone Giant was conducted opportunistically as continuous outcrops were limited or difficult to cut with the handheld core saw. The exposures are also in a large wash where the spodumene is evident but degraded due to erosion and seasonal water flow. The best sampling comes from 3.60m of 0.05% Li2O, with 385ppm Cs. The highly elevated Cs is an excellent indication of well mineralized pegmatite, but where lithium is locally weathered. The area remains a viable target as prior grab samples contain up to 0.43% Li2O and spodumene is visible over several outcrops on the pegmatite.

Recon Sampling

A new target called Ruby Soho was discovered, located 350 meters east of Lone Giant, consisting of 250 meters of exposed pegmatite. The seven samples collected along the 250-meter stretch have a lithium oxide range from 0.25% to 3.57% Li2O on a pegmatite that ranges in widths of 1.5 to 5.0 meters on the surface. This target has never been drill-tested and has road access to the highest-grade samples. One sample from the Thunder target ran 3.97% Li2O on a north-south trending pegmatite that has not been drill-tested. This pegmatite has limited strike length and good road access for future drill-testing.

QAQC

Channel samples were cut in the field under the supervision of Joey Wilkins. Sample location sites were labelled, rock channels were bagged, tied-off, then transported to the core shed under lock and key. Samples were shipped by the Company directly to SGS Laboratories in Burnaby, B.C., Canada where SGS prepped then analysed all samples using sodium peroxide fusion combined ICP-AES and ICP-MS, method GE_ICM90A50. Certified standards were inserted into the channel and rock chip sample stream and reviewed by the Qualified Person. Mr Wilkins consents to the inclusion of the technical information in this release and context in which it appears.
